Description of problem: DWH is now a dependency of engine. We need to try and improve its resources consumption so it will not impact engine performance.
Can you provide any additional information what will be contained within this RFE? Should we consider scale environment or just standard setup, clean DWH or under load? Can we define here what's the criteria for the RFE? What is the desired result?

Essentially running the JVM in a similar manner to how the engine is running (XMS and XMX setting for Java). > > Can we define here what's the criteria for the RFE? What is the desired > result? Less (virtual) memory usage, hopefully better CPU utilization. We'll test these on RHEV.TLV (which is using the full mode DWH.
Please test this by adding a new conf file to ovirt-engine-dwhd.conf.d : DWH_JVM_ARGS="-Xms1g -Xmx1g" and restart dwh service. Please how this affects the resources utilization on a scale environment. Also this should not affect production environment so can be tested on an internal production environment. It can be tested on a 4.0 environment as well.
Opened separate bug for limiting heap size testing.
Shirly - I believe this can be moved to ON_QA now?
all the dependant bugs in verified moving this as well
